As shown in Fig. 1, the unwashed cell suspension of B. megaterium
was the most effective treatment on control of the rots in peanut
kernels caused by A. flavus. After 7 days at 28 °C, the disease incidence
of the water control and autoclaved culture were both 100%, whereasthe treatment with the unwashed bacteria cell suspension at
1×108 CFU/ml was 36.67%±5.77%, which was significantly lower
than the treatments with the autoclaved culture, culture filtrate and
water control. Meanwhile, the average percentage of the disease
incidence in the treatment with the washed cell culture mixture was
41.67%±2.89%, which also showed remarkable decay control compared
with the treatments of water control, autoclaved culture and
culture filtrate (p
